gasoline smell on cold start

hi guys,

just noticed a very strong (raw) gasoline smell when starting my car for the first time today. i only had to back the car up just a foot, so as soon as i stepped out, the smell hit me. it's about 60 degrees out, so it's not particularly cold. i sniffed around, and the smell definitely smelled strongest by the exhaust pipes.

is this normal? i don't normally get out 10 seconds after starting a car, so i may have just never noticed.

the car is a bone stock 330i, fully equipped, AT, and out of warranty (60K miles). it's had a handful of issues, but none related to fuel yet. although i do sometimes get a very hard shudder at idle/stoplights. not a constant rough idle shudder, but a straight-up "was that an earthquake?" shudder. never any CELs or codes though. dunno if that's fuel related.

anyone have any insight? i don't know of any good independent shops around here yet, and would rather not do the whole dealer thing if it can be avoided.

thanks,
dave

Did the smell go away shortly thereafter?

hmm, i actually don't technically know yet, i'll check next time i drive it.

i did just move it back (again, just a few feet, so it was only running for a few seconds), and i smelled it just the same as the first time. but of course, that would still count as being cold.

i've never noticed it before, and i normally drive for more than a few seconds, so unless this is a totally brand-new issue as of today, it's safe to guess that the smell goes away when warm.

You just had a bit of unburned gasoline there.

Sounds like you may have a slight mis-fire, which would give you a un burnt fuel smell (I know these car should shut down the fuel to the mis-firing cylinder) I guess if the mis-fire is for a very short time you may still smell the fuel, as the ECU may not have time to shut the fuel off fast enough, this far fetched but just a thought.

i wouldn't start the car to back it up a foot, unless you have to. Cold starts that last for a couple of seconds are no good for the car's engine.
In fact i would put it in neutral, and then slip my foot out the door, and slide the car back a foot. Then again, i'm nuts.

no, i'm with you. i'm nuts like that too, but i didn't have an option. hate starting the car briefly, i almost feel guilty getting the computer and everything up and running just to shut it down again. yes, i know, weird.

John, can you share more detail on what happened with yours then? Presumably you got it fixed and whatnot? I'm afraid it's a problem as well, but I'm a certified car-hypochondriac.
